IIVIPROVEMEEINT IN SASH-IEASTENER.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom "it dawg/concern Be it-known that I, JOHN H. DoUeLAss, of Meriden, in the county of New Haven, and State of Connecticut, have invented a new Improvement in Sash- Fastener; and I do hereby declare the following, when taken in connection with the accompanying drawings, and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute `part of this specification, and represent, in-` Figure 1, a side view;

Figure 2, a face view; and in Figures 3 and 4, inside views, in different positions.

This invention relates to an improvement in apparatus for locking windows, and for holding them suspended at any desirablepoint, and consists in the arrangement 'of a bolt, combined with a lever, and a follower, which actuates both the bolt andlever, and these ,combined witha roll, which rests upon an in: clined surface, and between the said inclined surface and the edge of the sash, so that the said roll, borne down by the weight of the sa/sh, between the sash and. the said inclined surface, will hold the sash suspended, and arranged so that the said lever will raise the roll, to permit the lowering of the sash.

To enable others toconstruct and use my improvement, I will fullv describe the same, as illustrated in the accompanying drawings.V

A is the case, within which the mechanism is placed, its face, O, being formed with an incline, as seen in fig. 1, that is to say, so that, when the case is inserted into the window-jamb, the face-plate, or a portion of it, will be inclined to the sash B.

Within the case is arranged abolt, D, with a spring, E, which forces it out, as seen in lig. 3, and in immedateccnnection with whicha follower, F, is arranged so as to receive a spindle, H, through the window frame,

by means 'of which, with a suitable handle, the follower F may be operated to draw in the bolt, by moving from the position in fig. 3 tothat in iig. 4.

Within the case is also arranged a lever, I, operated by the follower F, so that, at the same time the 4 bolt is drawn in, the lever I will be raised,'as from .the position ing. 3 to that infig. 4, the said lever being forced down by a spring, G, or an equivalent device.

The case is inserted into the window-j amb in such relative position to the sash, that the face-plate O will be inclined thereto, as seen in: fig. l; and upon the said incline, and between that and the sash B, I place a roll, L, of suitable material, and of such size as to rest upon the incline and bear against the sash, the weight of the lsash forcing the roll down, and so that, when at its lowest point, the roll L will lie above the lever I, las seen in fig. 3. At any point where it is desired to lock 'the sash, a hole is' bored into the sash, to receive the bolt l), as seen in fig l.

.In this position, V-to raise the sash, turn the spindle H, to withdraw the bolt; then the sashis free to 'be raised; but, left withoutbeing secured by the bolt, the sash itself will fall until the roll is carried down the incline-face, until at such point the roll will wedge the sash hard against the opposite side, and will hold the sash suspended. And to lower the sash from that point, turn the spindle II, to raise the lever I, in which operation the lever strikes the roll, and raises it to the position seen in igA, or to such a point as will free the sash from its control, ,and thus the sash may be held at any point withinits extreme limits.

It will be observed tl1at"tl1e lever I and roll may be used without tle bolt E; but in such case there is no security to prevent the raising of the sash. I therefore prefer to combine therewith the bolt D.

yHaving thus fully described my invention,

What I claim as new and useful, and desire to secure by Letters Patent, is

The follower F, bolt E, and lever I, combined with the rollerL and incline C, when constructed and ar-` ranged to operate in the manner and for the purpose substantially as described.
